In the submission rules for 2 Player there is a line stating "If one of the players game overs the run is invalid. Two players must be present throughout the duration of the whole run. I have two questions about this:

1. If one player game overs, if they immediately steal a life is the run still valid?
2. Can an intentional game over be taken in the event that a player game overs/ no more lives are available to steal?

Looking at some of the 2 Player runs it looks like both 1 and 2 are allowed, but I'd like to be clear on the rules before starting learning the game.
